Mate, know the feeling.
A few months back, I was walking back to my car. Noticed a red plastic thing stuck my rear wheel. Thought it was some choc bar wrapper or something.
Took a closer look and peeled it off - it was paint! All the layers including the primer. Someone had reversed into me, scratched the car above the arch (which I can't polish out despite painting over it).
Gutting.
The sooner you get it sorted, the less painful it is.
